Young plant stress advice needed

  1. Do you think missing one days worth of dark period (4 hours) on a 1 week old would have an impacting amount of stress? Seems like there pretty resilient but I really don't know. What do you think?
     
  2. Like instead of 20hrs light it gets 24hrs light?

    That should be fine. Seedlings like their light.
     
  3. No problem at all. Lots of people veg their plants under 24 hours of light.

    Cannabis is a C3 plant, so it does not need darkness to photosynthesize. A dark period is only required to trigger flowering.
